CLEVlS.

SPECIFICATION forming part of Letters Patent No. &79,208, dated. July19, 1892. Application filed March Zl, 1892. Serial Nox &25,844. (Nomodel.)

To all whom it may concern:

Be it known that I, JAMES M. ENSCHED, of Crete, in the County of Salineand State of Nebraska, have invented certain'useful Improvements inClevises; and I do hereby declare that the following is a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

This invention has relation to a new and improved clevis.

The object of my invention is to provide a clevis in which the pin shallbe adjustably and detachably held, the object being more particularly toprovide a clevis embracing the points of cheapness, utility, andSimplicity.

In the accompanying drawings, Figure l shows a sectional View of myclevis having the pin inserted and in its locked position. Fig. 2 showsthe pin in its position preparatory to being withdrawn from its lowerseating in adjusting the draft link or tree. Fig. 3 is a top View, Fig.4 a bottom View, and Fig. 5 a sectional View, of the pin on line xx,Fig. 1.

A represents the stirrup, which may be of any suitable metal, size, orconfiguration, which is provided at the upper stub with an enlargementB. The lower stub is approXimately the thickness of the stirrup. Passingthrough the terminal ends or stubs of the clevis are two registeringcylindrical openings adapted to accommodate the metallio draft-pin C.Within the lower stub the opening is interrupted by the senicircular lipD, (shown in Fig. 4,) which projects into the opening a suitabledistance. The upper stub-opening is clear, but provided with apin-opening upon the side, which passes through the upper opening, so asto accommodate a pin D', which forms a transverse semicircular ribwithin the stub corresponding to the lip D.

The draft-pin comprises an upper thumb portion e' and a stock c. Nearthe upper end I provide a circunferential groove a, and eX- tending fromthis groove I mutilate or remove part of the stock of the pin, so as toget the fiat draft-surface a', as shown. This 5o surface ends near thelower end, so as to provide the cylindrical bearing portion b, belowwhich I provide the groove b', and extending from this the fiat portion?7 Now when both the clevis and pin have been constructed as described Iinsert the draft-pin C into its seatings, adjusting it so that the lip Dwill readily work past the flat portion 11 and rest within the grooveb', as clearly shown in Fig. 2. The pin D' is now inserted, which passesthrough the upperstub and partly rests within the groove a, as will beunderstood by referring to Fig. 3. In this position the pin C may bereadily removed from the lower stub; but it can only ride in oneposition, as the fiat surface a' checks the adj ustment, and pin D',whichis riveted within its seating, prevents the pin C from beingremoved from the upper clevis-seating. After the draft link or tree hasbeen inserted, the pin C is turned one hundred and eighty degrees, so asto present the fiat surface a'to the rear, as shown in Fig. 1, in whichposition the lip D works into the lower groove b', and so securely looksthe pin within the clevis. The clevis is not weakened by the insertionof the pin D', as this pin is without the bodyline of the clevis.

Having thus described my said invention, what I claim as new, and desireto secure by United States Letters Patent, is-

1. As a new article of manufacture, a clevis the stubs of which areprovided with registering pin-openings, in combination with a draftpinworkingwithin said pin-openings,provided with an upper groove and a fiator mutilated portion extending from said groove, and a pin passingthrough the side of the upper stub and resting partly within the grooveof the draft-pin, substantially as described.

2. As a new article of manufacture, a clevis the stubs of which areprovided with registering openings adaptedvto contain a draft-pin, thelower stub being provided with a lip projecting into its pin-opening, incombination with a draft-pin working within said opening provided withan npper circumferential groove, a mutilated portion extending asuitable distance from said groove, and a lower circumferential grooveleading into a mutilated portion below, said lower groove being IOOadapted to aocomnodate said projecting lip groove b', and the mutilatedportion b", all and the upper groove a non-removable pin, allsubstmtially as and for the purpose set forth. 10
